JEHU MITCHELL, OF ALEPPO TOWNSHIP, PENNSYLVANIA.

CHURN.

Specification of Letters Patent No. 27,927, dated April 17, 1860.

To all whom it may concern:

Be it known that I, JEHU MITCHELL, of Aleppo township, in the county ofGreen and State of Pennsylvania, have invented a certain new and usefulImprovement in Churns; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, making part of this specification, in which-Figure 1, is a perspective view. Fig. 2 is a vertical section showingthe beater shaft entire.

A is a tub'of ordinary construction with a lid or cover made in twoparts B and C and fitted in the top.

D is a standard mortised into and firmly secured to one part of the lid.The back part of said standard projects higher than the front and formsa support and bearing for the axle of the driving wheel E. In the frontof the standard D one half of a vertical journal box is formed, theother half or cap G is hinged at one side in such a manner as to permitthe ready removal of the shaft suspended and working therein by simplyunhooking and swinging open the cap of the box.

H is a hook and I a pin or eye attached to the standard and caprespectively for the purpose of keeping the latter closed.

J is the dasher shaft extending nearly to the bottom of the tub havingupon it two collars K, L, one beneath the pinion M and resting on thetop of the box and the other just below the bottom of the cover, toprevent a vertical motion of the dasher shaft and also prevent the creamfrom being thrown upon the journal bearing of the shaft J. The pinion Mmeshes into cogs on the driving Wheel E through which motion iscommunicated to the dasher shaft.

N are dasher wings and O brakes of common construction.

In order to remove the dasher from the tub the part B of the lid islifted out first then the cap of the box unhooked when the dasher can betaken out for the purpose of inspecting the butter or cleansing thechurn without the necessity of removing the driving gear or the mainportion of the cover.

Suspending the dasher within an elongated hinged journal box in themanner described,

combined the following advantages. A rigid bearing is aiforded to thedasher so as to prevent any tremulous motion, without the necessity ofany metallic step or bearing within the churn, the oxidation of whichimparts a bad flavor to the butter. The dasher may be readily removedfor the inspection of the cream or cleansing the churn, without removingthe gearing and main part of cover. The vertical and horizontal shaftbeing journaled in one standard common to both gives durability and caseof motion with great economy of construction.

I do not claim broadly the construction of a churn without a step atbottom, neither do I claim novelty in mounting a journal in a hingedbearing irrespective of the connection and purposes herein shown, but

What I claim as new and of my invention as an improvement in churns isThe arrangement of the gearing E M, standard D hinged caps Gr verticaldasher J N, and collar L, the whole being constructed and combined inthe manner and for the purposes hereinbefore set forth.

. In testimony of which invention, I hereunto set my hand. I
